Prepare the source and define the result
Photograph straight on, keep corners visible and use diffuse light. Crop background while retaining borders, headings, footnotes and units.
Set acceptance criteria before processing: expected pages or records, languages, critical fields and destination format.
Use a reviewable OCR workflow
Correct perspective before rotation and contrast. Check lines against the preview grid and avoid removing decimal points or thin minus signs.
Keep recognition evidence beside the source. Confidence prioritizes review but does not guarantee a word or number.
Verify before using the output
Inspect small text and far corners at full size, then sample every column. Split independent regions if one grid remains unstable.
Keep the original until the reviewed derivative is accepted. Valid structure does not prove semantic accuracy.
- Shadows can look like column boundaries.
- Thresholding can remove punctuation.
Put the workflow into practice
Arrange source documents, select the pages you need, and create one PDF locally in your browser. Review the result before choosing any optional next step.
